' ATTOR'NE Patented Nov. 13, 1934 UNITED STATES MEANS FOR onrArNr'Ne-rcn niiooxs FROM AN AUTOMATIC TYlf'E REFRIGERATOR Leon S. Brach, East Orange, N. J. Application March 15, 1932, Serial No. 598,904 4 26 Claims. ((31. 62- -1085) This invention relates to ways and means for obtaining ice-blocks from an automatic refriger- ,ator. By an automatic refrigerator, I mean one in which the cooling compartment is cooled by an expansion member such as found in the present-day electrically operated refrigerators.

As far as I am aware, it is now the practice to freeze ice-blocks or cubes as they are generally called, in trays having a plurality of integral compartments, or compartments formed by a movable separator whereby the water will be frozen into blocks or cubes. Consequently, when pens that only a veryfew blocks or cubes aretype refrigerator with the door to the coolin it is desired to use these ice-blocks, it is necessary totake the whole tray out of the refrigerator, and. if the tray is a metal one it must be warmed by having hot water run over it or in some other manner; whereby the ice-blocks may be ex-' tracted or allowed to fall out. It frequently haprequired but this necessitates removing the whole tray just" the same.

The principal object of my invention'is to provide -a method and apparatus or means for generally obtaining from an automatic refrigerator one ice-block at a time, although from what will be later said, it is within the scope of my invention to obtain a plurality of cubes'simult'aneously if desired.

While attaining the principal object, it is another object of my invention to provide means for automatically filling with water the containers from which the ice-blocks have been removed. 4 I I Another object of. my invention is to provide means for pre-cooling the water before it is passed to the empty containers, whereby the freezing process may be expedited and more assurance given of a supply of ice-blocks.

-Another object .of my invention is to provide means by which ice-blocks may be obtained or delivered from the refrigerator by the mere actuation of a lever operated by hand or foot-or the mere placing of a receptacle in position to receive the ice-blocks or cubes. These operations may be performed without the necessity of opening the refrigerator whereby the interior temperature would be raised.

-In addition to these general objects, other and further ancillary-objects will be discerned by one skilled in the art of refrigeration on reading the specification taken in connection with the annexed drawings wherein:

Figures 21 to '34 inclusive, illustrate diagrammatically the various steps in the progress of the ice-block containers through the refrigerator.

Figure 35 is a front view of the refrigerator showing a foot-control for extracting one of the ice-cubes from the refrigerator.

Figure 36 is a side view of the foot-pedal mechanism shown in Figure 35.

Figure 37 is a view similar to Figure 35 but showing how the ice-cube may be obtained from the refrigerator by the mere insertion of a glass or other receptacle in the receiving position.

Figure 38' is a fragmentary section showing the electrically operated means for ejecting an ice-cube by the insertion of the glass as shown in Figure 37.

Figure 39 is a view similar to Figures 35 and 37 by illustrating how a pair of ice-cubes may compartments 2 closed by the door 3, equippedwith the usual expanding coils 4. As illustrated, the condenser may be placed in any desired position, one such being shown by dotted lines 5 within a cover 6. As shown in Figure 1, the compartment 2 shows a row of ice-block containers 7. A pre-cooler 8 and extracting plunger 9 are supported in a bushing 10. 1A chute 11 is shown positioned in a recess 12 adapted to receive a glass or receptacle 13. In the recess 14 is positioned a hand-operated lever 15 which actuates the interior mechanism to be later described.

The containers 7 are preferably made of two similar metal pieces '16 (Fig. 18) which are pivoted together at the point 17. One of the metal pieces 16 is equipped with a lug 18 having a transverse slot 19 therein. The other piece (Fig. 3) is equipped with a lug 20 carrying .a. .circular pin 21. The purposes of these lugs -lugs 18 and 20. -The object of this construction a will be later pointed out in the operation of the device. 0

A plurality of theice-block containers 7 are assembled within the space enclosed by the expanding coils 4 and are held in tandem relationship by spaced guide pieces 24 and 25 (Figs. 4 and 5), and the side-wall pieces 26 and 27.

After; being positioned within the expanding coils'4 (Fig. 4), the containers 7 are coupled together as shown in Figure 14, whereby they may be pushed through the refrigerator as will be later pointed out. The details for carrying the ice-cube containers 7 through the refrigerator will perhaps be more readily understoodby describing them along with the description of the operation of the. machine.

In the description of the operation of the machine, it is assumed that we start as illustrated in Figure 4 with the ice-cube containers 7 in the following-set-up: All those within the expanding coils '4 are assumed to be thoroughly.

I with water. 8' and 9' are shown in'reverse position, 8' beingin the position wherein an icecube orblock is being ejected from the machine. A drip-pan 107 is preferably placed at the filling station or under the container being filled.

Starting with the apparatus in this position, a downward movement of the lever 15 or the footpedal 28 connected to a. rod 29 (Figs. 35 and 36), actuates a gear 30 (Fig. 10) carried on the shaft 31 to which the. lever 15 is attached. The turning of the gear 30 turns the gear 32 used for operating the mechanism shown in Figure 8, but because of the dental type of clutch 33, nothing takes place in the apparatus shown in this figure on the down-stroke of the lever 15. However, idler gears 34, 35, and 35' are operated which in turn operate gear 36. The gear 36 is connected to a shaft 37 carrying a lever 38 to which is attached plunger rod 9 (Figs. 7 and 19) carried by bushing 10 (Fig. 4). The plunger 9 will be forced downward, forcing the icecube or block out of the container? as shown in Figure 20. At the same time, the plunger rod 9 actuates the forked end 39 of a valverodwhich operates the container filling valve 99. The metal edges 23 of the cup are shown in sliding position on the support piece 40. It may be noted at this point that by constructing the container so the edges 23 as described have a metal surface engaging another metal surface,

allows the containers to slide easily thereon;

If the soft rubber would engage the metal support 40, it would'not readily s'lide thereon.

It should be noted that the shaft carrying.

the lever 15 also carries a lever 41, the shaft not being shown in Figure 12. Pivotally mounted at 42 on the end of the lever 41, is. a pawl member 43 preferably having a rounded nose which strikes the end of a lever 44 pivoted at- 45 (Fig. 11) and operating in .av slot -46 in a frame-piece 47-, but becausev of the pivot 42,

the pawl 43 will pass the lever 44-on the .downward stroke of the main operating handle or. lever 15.

After the ice-cube or block has been ejected into the chute 11 asdescribed, the handle 15 is released and a tension spring 48 (Fig. 7) will pull the levers 15 and 41 back. to normal position. However, on the first part of -the return stroke of the lever '41, the pawl 43' ene gages the end of the lever 44 and causes this to actuate a bell-crank lever 49 pivoted at-50 One arm of the bell-crank lever 49 engages a roller 51 carried on an arm 52 attached to a rack 53 which is in engagement with pinions 54 and 55 (Figs. 4 and 11), thereby turning them.

with the container 9' (Fig. 4).-in the same manner, ltmay be noted at thispoint that the containers.

is connected to the arm '74 through a lost mothe rack 61.

containers '7' and 8' (Fig; 4) are both guided on the side opposite to the pinion 54 by a guide-rail 57 having a guide-slot 58 therein (Figs. 15 and 16) to receive the 'pin 21 (Fig. 3) of the container 7. Another guide member 59 is indicated in Figure 16 to guide the opposite side of the containers when they are in the discharging position 8. The rotation of the pinion 54 as previously described, will turn the container 7 having a frozen block therein upside-down ready to be advanced to the position 8'. Likewise, the pinion 55 will turn thecontainer 9' which at the beginning of the upstroke is in an upside-down position and has been advanced tothat positionfrom the position 8', and the container 9 will then be in position to be moved forward-into the waterfilling line.

On the second part of the up-stroke of the lever 41, the gear 30 operates the gear 32 in reverse direction and the clutch 33. will then pick up and rotate the pinion 60 in mesh with The rack 61 carries an arm 62 having a collar 63 in engagement with a lever arm 64 pivoted at 65. Connected to the arm 64, is a rod 66 carrying a finger 67 operating 9' for the purpose of advancing the same as.

will be later described. Rigidly connected with the lever arm 64, is another lever arm 69 carrying a rod 70 to which is attached a finger or roller 71 corresponding to. 67. This finger is carried in a slot 72 in a guide-way 73 (Figs. 8 and 5). The finger 71 is shown in position also in Figure 4 behind the container 16'.

Also rigidly connected to the lever arm 64, is an arm '74 to which is attached a rod 75 connected through a coupling member 76 (Fig. 17) with an advancing slide .77 having projections 78, 79, 80, preferably pivotally mounted thereon and each held in the positionshown in Figure 17 by a similar spring 81. The bent or curved ends of the projections 78, '79, and 80 operate in back of the containers 1', 3', 5", just the upper edges, thereof. engaging the bottoms of the It will be noted-that the rod '75 tion arrangement comprising a slot, 82 in the end-rod 75 within which the connecting pin 83 may operate. Likewise, the rod 66 is connected to the arm 64 by a similar arrangement.

The movement of the rack 61 to the lever 62,- will operate all of the lever arms 64, 69, and '74,

and the corresponding connecting rods 66, 70, and '75. The movement of ,the rod 70 will first advance the containers 16', 1'7, 18' to the position shown diagrammatically inFigure 23, and because of the lost motion in connection on the rods 66 and 75, the three containers just mentioned will be moved out of the wayand theof the container 5, it is moved into mesh with' the ,pinion 54 as previously described, ready to be turned over by the next downward movement of the lever 15 as has been described. Likewise, thecontainer 8 is moved intomesh with the pinion 55 to be turned right-sideup on the next downward movement of the lever- 15 as has been explained.

After three movements of the slide 77, the containers 1', 3', 5, will all be moved out of overlapping engagement with the containers 2', 4', 6', the same being the first cross-row within the confines of the expanding coils 4. Consequently, on the next or the'fourthmpward movement of the lever 15, the three containers 2, 4, 6', will be simultaneously advanced into the position as shown in Figure 32. 'This movement takes place before the second part of the\upstroke of the lever 15 and associated mechanis is completed, andthis advance is accomplishe by the mechanism shown in Figure .9 wherein the gear 30 is associated with a dental clutch 84 which will now function to turn the pair of gears 85 and operate the arm 86 connected with a slotted lever 87 carrying an arm 88 to which is connected a rod 89 having a connection 90 operating .in the guide-slot 91 in guide-way 92. The connecting device 90 is associated with an arm 93. which in turn operates a slide-bar 94 that is adapted to engage any three containers; for example, 16', 17', 18', after they have been advanced to the space in alignment with the opening between the expanding coils 4, or in the position as illustrated in Figure 31. It is to be noted that in the starting off of the apparatus as above described, while the containers 2, 4, 6' were advanced during the fourth cycle, it will be seen by Figure 34 that thereafter the advance of the three containers as shown in Figure 32 will take place during each third cycle.

It is to be noted that while the gears 85 are actuated-each timevthe lever 15 is returned, the

ing the up-stroke of the lever.41, thereby setting the pinions 54 and- 55 in position to receive the containers as they are advanced by the actuation of the rod '75 and the slide member 7'7. 1

It is to be noted also that as the slide member 77 is operated to discharge the containers in the row 1, 3, 5, which containers are individually engaged by the clips 80, '79, and '78 .respectively as the slide member '77 is' .moved backward on the return movement of the lever 74 under the action of a spring 97, the turnedover end of these clips will pass underneath the containers in front of them. .For example, the

clip 79 will move forward its container 3' and then on the return movement of the slide '77, I

the clip 79 must pass under the containerl in order to engage. it to advance it on the next advance stroke. Therefore, the clips 78, '79, and 80 are-pivoted to allow them to tip over against the very lightsprings 81 so that they will pass" 5) during the' actuation of the operating lever 15 so that as the containers come along intothe proper position as indicated, they are filled with aregulatd quantity of water which is measured by the valve 99.

Figures 21 to 34 inclusive illustrate diagrammatically the various steps in the operation of the mechanism. -For example, Figures 21, 22, and 23 indicate one cycle of operation which may be briefly restated as follows:

upside-down position in Figure 21, has been turned by its pinion 55, the valve 99 has been closed on the discharge side and filled from the pre-cooler 8. In the final or second up-stroke of the lever 15, the containers are advanced as shown in Figure 23, and the parts are now ready for the second cycle of operation which is indicated in'Figures 24, 25, and 26.

The third cycle is illustrated in' Figures 2'7,

28, and 29, and the fourth cycle in which three of the containers are moved forward to be engaged by the advance slide 77 and in which the three containers 16, 1'7, and 18' are to be advanced into the freezing position, is illustrated in Figures 30, 31, 32, and 33.

Figure 34 illustrates the next cycle following the end of the fourth cycle, at the end. of which cycle the single row of containers has been advanced as shown in Figure 34 which corresponds to Figure 24, and as has already been explained, the advance of three of the containers out of what I have termed the freezing position of the space enclosed by the coils 4, will then take place thereafter on each return cycle. In Figures 3'7 and 38, a glass or other receptacle 13 may be inserted into the recess 12 to actuate a' switch lever 102 for closing contacts -103 which will operate a small electric motor 104 to] actuate the mechanism or modifications thereof as previously, described.

It is to be understood that the closing of the switch contacts 103 will put the motor 104 into operation and only one cycle of operation of the mechanism hereinbefore described will be made; that is to say, after the" lever 15 or equivalent thereof has been operated by the motor to eject an individual ice-block or a plurality of iceblocks if the mechanism is arranged to do so as illustrated in Figures 39 and 40, the other mechanism will only function as hereinbefore described. Preferably, the motor will be arranged to stop after it has performed its one cycle of operation.

In Figure'39, the recess 12 is provided with a table 105 which will actuate a lever 106 controlling the aforesaid mechanism, so that when a glass or receptacle is placed on the table 105, a slight pressure on the glass or receptacle will start the mechanism into actuation. Two such devices are indicated and may control duplicate sets of parts as previously described.

In Figure 40, one of the plates 105 may be arrangedto actuate .more than one set of mechaapparatus may be varied over wide limits, and

I therefore do not wish to be .unduly limited further characterized in that the containers are in the, interpretation of the scope of the appended claims.
